Coldplay singer Chris Martin joined forces with R.E.M. frontman Michael Stipe for a special performance of 'Losing My Religion' during the 12-12-12 Concert for Sandy Relief at Madison Square Garden. According to NBC anchor Brian Williams, who appeared onscreen soon after to solicit donations, the team-up was a surprise even to those involved with the planning, and Martin himself seemed humbled to share the stage with one of his heroes.
